Title
C-arm based computed tomography—A comparative study
Abstract
For optimal outcomes following osteosynthesis proper positioning of inserted screws is required. Especially close to curved joints the standard control of screw positions, i.e. intra-operative C-arm fluoroscopy and post-operative X-rays, can leave misplacements undetected. A new mobile C-arm allows 3D imaging (C-arm-CT) and promises to intraoperatively close this gap in 2D-information. Insertion of screws into four cadaver specimens simulated the treatment of talus neck fractures. Twenty physicians evaluated X-ray, C-arm, C-arm-CT and CT images. The best image quality was shown by X-rays (p<0.001), followed by C-arm and CT, and the C-arm-CT being rated lowest (p<0.001). The most correct diagnoses were obtained with the statistically not different CT and C-arm-CT, while C-arm was inferior (p<0.001) and X-rays being the worst (p<0.05). Although the image quality is poor, in detecting screw misplacements the C-arm-CT was as suitable as CT and clearly superior to the current standard procedures. At least at the extremities, probably at the torso too, the C-arm-CT will support the further development of open and minimally invasive surgical procedures.
